Letters Patent No. 110,994, dated January 17, 1871.

IMPROVEMENT IN MATERIAL CALLED OLE lZERINE, FOR DYEING AND PRlNTlNG.

The Schedule referred to in'these Letters Patent and making pan: of the same.

To all whom it may concern.- 7

Be it known that I, ALFRED PARAF,'0f-Fl'm10e, now residing in the city, county, and State of New York, have made an invention or discovery of a new and useful article of manufacture or composi- 'it has the characteristics of the Turkey red produced by dyeing cloth with a compound 'of madder and oil.

Ole-izerine may be. prepared in the following manner:

Dissolve one part, by weight, of parafiinc in two parts, by weight, ofreliue'd petroleum, or the same quantity of kerosene.

-Boil one part, by weight, of dry garanciue with three parts, by weight, of the above mixture for half an hour, continually stirring the mixture.

Separate the solution by straining the product by means of a cloth, v

,Boil the partially-cxhaustcd garancinc with three additional parts of the above mixture, in the same manner as before, and separate the solution by straining the product by means of a cloth, using pressure to separate the last portions of the liquid.

Permit the solution, as it is strained, to run into water, the quantity of water which may be used with advantage for this purpose being about eight times the weight of the garaucine employed.

The solution rises to the surface and floats upon the. water. i

Stir into the mass a saturated solution of caustic soda, in water, in sufiicient quantity to cause the coloring-matter to separate from the hydrocarbon solvent, and to dissolve in the water.

The soda solution is added, drop by drop, untilthc effect is produced, a slight excess being notinjurions.

If a sufficient quantity vof the soda solution has not been added, the hydrocarbon which floats on the top of the water will remain colored, in which case an additional quantity of the soda. solution should be ap- )lied. 1 1 If the required quantity of soda solution has been employed, the hydrocarbon is left practically colorless, floating on the surface of the aqueous solution of the col oringj-matter.

The liquid is allowed to settle after the addition of l the soda solution, and ,the aqueous solution is separated from the hydrocarbon by drawing olf the former or by decanting the latter. The hydrocarbon .may

then be used again for treating a new quantity of garancme.

' The aqueous solution is treated with an acid that will combine with. the soda and cause the precipitation-of the coloring-umtter. The acid preferred for aqcous' solution, drop by drop, until no further precipitation ensues. The precipitate is then separated from the liquid by means of a cloth filter, and is thoroughly washed with water on the filter.

moist state. It may be used in that condition, or may be previously dried by exposure to air, with or without the aid of heat.

Instead of treating the garaucine with petroleum treated with a potrolcuu1-oil, such as kerosene, without paraliiue. Kerosene boiling at a temperature of from 300 to 3MP l ahrcnheit is well adapted to this purpose.

Tile operation may be conducted in the manner above described, and the olc-izcrine may be obtained from the fluid extract, as above described. Or, instead of permitting the kerosene solution to run from the filters into water, it may be collected in bulk, and mixed in a vat with an equal quantity of boiling water. An aqueous solution of caustic soda at 6 Baum, in the proportion of one-quarter of one per cent. of the mixture, is added to it, and the whole is thoroughly mixed by stirring it. The mixture is then permitted to settle, the aqueous solution is separated from the kerosene, and is treated with an acid, and filtered, as above described, to obtain the ole-izerine.

The article or composition of matter denominated ole-izerinc is not restricted by the process orby the means employed in producing it, as these maybe varied. Moreover, the material may be adulterated, by incorporating other. articles with it, without materially ularl y valuable for the purpose of mannfitcturing mader colors for printing fabrics, and for this purpose it may be manufactured into rubidide.

I claim as the invention to be secured by Letters Patent- The new article of manufacture denominated oleizerine, and hereinbcfore described.

In testimony whereof-I have hereto set my handthis 13th day of September, A. D. 1869.
